I have recently purchased an 'almost complete' restore of an '86 Bertone. Yea - it's a good thing. But here's the ya-ya: It takes forever - up to 15 cranks - or a push - to start in the morning. After that, it runs so sweet. But then, after warming up real nice, it starts to run ragged, sputtering on acceleration. THEN, the Volt meter will drop & the water temp will rise - both at the same time. Sometimes, they will even return to normal BOTH at the same time. Do they (water pump & alternator) run off the same belt? Any input will be greatly appreciated.
